## What it is
Shardeum is an EVM-compatible Layer 1 blockchain platform that uses dynamic state sharding for horizontal autoscaling, low fees, and fast finality. The repository contains the core network software for running local networks and nodes, with JSON-RPC endpoints, MetaMask compatibility, and support for deploying Solidity smart contracts via standard Ethereum tooling.

## Use cases
- run an EVM-compatible layer 1 blockchain node
- deploy solidity smart contracts on a sharded network
- build dapps with low predictable gas fees
- tokenize real-world assets onchain
- run a validator node and stake SHM
- spin up a local multi-node blockchain network for testing
- connect MetaMask to a scalable EVM chain

## When to choose
- you need an EVM-compatible chain with horizontal scaling through sharding
- you want low, stable transaction fees for high-throughput dapps
- you want to run validator, full, archive, or RPC nodes
- you're building real-world asset tokenization or payment applications
- you want to reuse existing Ethereum tooling like Hardhat, Foundry, and Remix

## When to avoid
- you need the most battle-tested, maximally decentralized smart contract platform (Ethereum mainnet)
- you want a non-EVM or non-Solidity development model
- you need a lightweight library to embed in an application rather than network infrastructure
- you can't meet node hardware requirements (16GB RAM, 1TB NVMe for validators)
- you require a long-proven track record of mainnet stability
